Abstract (en)

[origin: EP0801430A1] As a nickel electrode for alkaline storage batteries, an electrode plate comprising a plurality of electroconductive substrates and a plurality of active material layers which are alternately laminated and integrated is used, whereby mutual electric conductivity of the active material and the electroconductive substrate in the direction of thickness is increased, and active material utilization, discharge voltage characteristics as batteries and charge-discharge repetition life are improved. The nickel electrode comprises a plurality of electrode leaves each of which comprises an electroconductive substrate coated with an active material and which are laminated and integrated so that the electroconductive substrate and the active material layer are alternated with each other, a plurality of said electroconductive substrates being electrically and mechanically connected through a part of the respective electroconductive substrates, said electroconductive substrate having a thickness of 5-60 mu m, said active material layer coated on the electroconductive substrate having a thickness of 20-250 mu m.
